You can use the GoFit GFEPGYM ProGym Extreme without a door anchor, but there are some things to consider. According to the manufacturer's description, it comes with resistance bands in different weights (20, 30, 40, and 50 pounds) and includes extras like handles, ankle straps, and door anchors. The door anchor is mainly there to help you do exercises that need a stable anchor, like rows or tricep extensions.
That said, you can definitely get creative if you don't want to use the door anchor. Our research shows a lot of folks finding ways to modify exercises using just the bands and handles. So, you can still do things like squats, lateral raises, and bicep curls by using your body weight for resistance instead.
However, there are some challenges. According to our data, not all door anchors fit every door perfectly, which can be a problem depending on your living situation. And without the anchor, you might have fewer options for certain exercises unless you're open to adapting them or adding some other equipment to your routine.
In short, you can make it work without the door anchor, but your exercise routine might feel a bit limited if you like doing exercises that need anchoring. It's a flexible system—just think about your space and what you're after with your workouts before deciding.
